Title: Surge absorber
Inventor: ONO TAIICHI
IPC: H01T1/20
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To shorten the response time till the start of discharging in a surge absorber in which a gap is formed between resistor layers. SOLUTION: Two resistor layers 12a and 12b are formed on the surface of the base 11 of a flat plate chip while a gap 13 is reserved in between. One of the resistor layers 12a is formed from a high resistance layer (a) while the other resistor layer 12b is set in low resistance in which a low resistance layer (b) is laminated on the high resistance layer (a). Because of low resistance of layer 12b, the time constant determined by this resistance R2 and the capacitance C of the gap 13 becomes short, and the gap charging time is shortened. This allows shortening of the response time till when discharge is started between the main electrodes. If the resistor layers 12a, 12b are covered with an electron emitting material layer 21, the response time can be shortened still more.

Title: Semiconductor nonvolatile memory
Inventor: SAITO KENJI
IPC: G11C16/16
Filed: 1993-12-02
Abstract: PURPOSE:To set a range of batch erasing efficiently by embedding a silicon oxide film in a groove forming a twin well, which has been formed in a memory cell region, on a Si substrate, and dividing it. CONSTITUTION:After a twin well 7 and 8 is formed in a specified memory cell region, a SiO2 field insulating film 3 is formed, then, a groove 1.5 separating the twin well 7 and 8 into a plurality of blocks. Next, the SiO2 insulating film is embedded in the groove 15. Consequently, the twin well 7 and 8 is separated by groove separation in a direction of the twin well 7 and 8 intersecting a word line orthogonally, forming blocks which become the erasing unit. This makes it possible to decrease an area for separation of erasing blocks. Also, because the erasing unit can be reduced, in the event of electrical batch erasing, a scattering in threshold value in the erasing blocks can be held small. Further, a chip area can also be reduced.

IPC: G11B7/00
Filed: 1988-11-29
Abstract: PURPOSE:To improve data transfer efficiency by providing a buffer memory for the part of alternative sector reading the data of the alternative sector, which corresponds to a defective sector, from the buffer memory for the part of the alternative sector and transferring the data to a host device when there is a defect in a source sector. CONSTITUTION:For example, there is the defective sector in a sector k+2 and a pattern to show the defective sector is recorded to a flag part. Then, the data of the defective sector are recorded to an alternative sector (r). When the data of the sector k+2 go to be sent continuously to a sector (k) and a sector k+1, a defective sector detecting circuit 4 executes the detection of the defective sector according to the pattern from the flag part and the defective sector is informed of a microprocessor 5. The microprocessor 5 controls an error correcting/detecting circuit 6 and stops the data transfer from the sector k+2. When there are the data of the alternative sector (r) to correspond to a defective sector K+2 in an alternative sector buffer memory 8, the data are sent to a data transfer circuit 7 and transferred to a host device 10. Thus, the data can be continuously transferred and the data transfer efficiency can be improved.

Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To simplify connection and improve assembly efficiency by providing a plane part formed at a piston so that a connecting rod does not protrude outside of the piston at the time of connecting a small diameter part, and a rotating shaft extended upright from a plane part so as to fit the small diameter part thereto. SOLUTION: A plane part 1 is formed at a piston 57 so that a connecting rod 58 does not protude outside of the piston 57 at the time of connecting a small diameter part of the connecting rod 58 to the piston 57, and a cylindrical rotating shaft 2 to which a small diameter part hole 62 of the connecting rod 58 is fitted is formed protruding from the plane part 1. The height of the rotating shaft 2 is so set that the rotating shaft 2 is not detached from a bore 56 when the piston 57 is positioned at the bottom dead center, thus preventing separation of the connecting rod 58 and piston 57. The piston 57 can therefore be connected only by a process of inserting the rotating shaft 2 in the small diameter hole 62 and inserting a crankshaft in a large diameter part hole 61, so that an assembly process is simplified.
